We are seeking a Senior Full‐Stack Developer to lead the implementation of a secure, highly available, and enterprise‑integrated single‑page application running on AWS. You will build a React‑based front end (with AG Grid), serverless APIs (API Gateway + Lambda/Python), and containerized infrastructure (Fargate + Nginx + ALB), with integrations to EPM, EDW, and Archer via REST APIs. You ll partner closely with architecture, security, data, and reporting teams to meet client standards around identity (Azure AD SSO), monitoring (Cloud Watch/Splunk), and reporting (Tableau on‑prem).

• Front End (SPA)
• Build responsive, accessible SPAs using React
  , HTML5
  , and CSS
  .
• Implement AG Grid for complex, enterprise‑grade grid use cases (virtualization, server‑side pagination, row grouping, custom cell renderers).
• Collaborate with Tableau developers to seamlessly link/react to Tableau (on‑prem) reporting surfaces.
• Design and implement RESTful services using AWS API Gateway and AWS Lambda (Python).
• Develop Python services for event‑driven workflows via Event Bridge + Lambda
  ; implement idempotency, retries, DLQ patterns as needed.
• Model and query data against Amazon Aurora (Postgre
  
  SQL/MySQL); design performant schemas, migrations, and SQL.
• Configure AWS Fargate tasks and Nginx for static content hosting and reverse proxy to services; integrate with Application Load Balancer
  .
• Implement CI/CD pipelines (build, test, deploy) for front end, Lambdas, and Fargate tasks.
• Apply Cloud Watch metrics/logs/alarms and Splunk dashboards/alerts for end‑to‑end observability.
• Security & IAM
• Integrate Azure AD SSO (custom OAuth/OIDC) for secure authentication/authorization across internal users.
• Apply security best practices: least privilege IAM roles, secret management (e.g., AWS Secrets Manager/SSM), input validation, and secure headers in Nginx.
• Enterprise Integrations
• Build robust, well‑documented REST integrations with EPM
  , EDW
  , and Archer systems.
• Implement resiliency (timeouts, retries, backoff, circuit breakers), thorough logging, and monitoring for integrations.
• Quality & Delivery
• Write unit/integration tests (front end & backend), ensuring high coverage and automated test gates in CI.
• Participate in Agile ceremonies, provide estimates, and deliver incrementally to production.
• Produce clear technical documentation (architecture, runbooks, API specs).

• 6–8+ years of professional software development with a focus on web applications.
• Strong React experience (hooks, state management, component composition, performance profiling).
• Demonstrated delivery using AG Grid in enterprise contexts.
• Python proficiency building serverless functions and data automations.
• Production experience with AWS services:
  API Gateway
  , Lambda
  , Fargate
  , ALB
  , Event Bridge
  , Cloud Watch
  .
• Hands‑on with Aurora (Postgre
  
  SQL/MySQL) including schema design, query optimization, and migrations.
• OAuth/OIDC experience integrating Azure AD SSO for internal apps.
• CI/CD experience (e.g., Code Pipeline/Git Hub Actions/Azure Dev Ops) and IaC patterns (Cloud Formation or Terraform).
• Solid understanding of security, networking (VPC, subnets, security groups), and containerization fundamentals.

• Experience hosting static SPAs behind Nginx with caching, compression, and security headers.
• Familiarity with Tableau usage from app workflows (URL params, trusted tickets, embedding patterns as allowed).
• Experience with Splunk queries, alerting, and dashboards.
• Knowledge of OpenAPI/Swagger
  , JSON Schema
  , and contract testing (e.g., Pact).
• Performance engineering for AG Grid (server‑side row model) and React (React Profiler).
• Data privacy/compliance practices in regulated industries (audit, data retention, PII handling).

• Strong ownership and bias for action; comfortable leading designs and code reviews.
• Clear, concise communication with technical and non‑technical stakeholders.
• Empathy for users and partners (security, infrastructure, data, reporting).
• Mentorship mindset—uplifts team quality and standards.

• SPA deployed…
